TO WHOM IT MAY CONCERN:

Be it known that I, LEWIS GRANGER, of Memphis,`in thecounty of Macomb, and State of Michigan, have invented a new and useful Improvement inSpring-Bed Bottomsl and I do declare that the following is 'a true and accurato description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, and. 'being'a part of this specification, in which Figure 1 is a perspective view, and

Figure 2 is a vertical transverse sectional view of the same, on the line X X, and the same letters indicate like parts in each'gure. i I

The nature of this invention consists in constructing` a spring-bed bottom of pairs of longitudinal slats, connected at their vends to a block which keepsfthem a'. proper distance apart, and allowing them to deilectrand spring without interfering with each other, theamount ot'E elasticity given-to the slats being varied as may be desired, by movingr the slotted transverse barsthrough which the lower slats pass to or from the cent-re of the bed.

VA, A are the side-rails of an ordinary bedstead, secured to which are the ledges B, which form a support for theslotted transverse bars C, passing through which, and sustained bythe same, are the elastic slats D, to the ends of which are secured the upper slats E, but kept' apart by the blocks F, placed between the upper andl lower slats at their ends.

G are stops secured to 4the head and foot-boards ofthe bed, securing the upper row oix slats to their proper positions, and preventing their rising up. when the weight 'of the bodyis superimposed between the Sldtied transverse bars C. By shifting the position ot' the transverse bars C, greater or less elasticitylin the head, centre, or foot portions ofthe bed-bottom is secured. y'

What claim as myinventiomand desire to secure by Letters Patent, isn I The combination and arrangement of the slats D and E and blocks F with the transverse bartC, in conneetion with any proper bedstead, and operating substanta'llir as described and for the purposes settorth.
